Description
Patentkrav Π-14): 1. Fremgangsmåde til fremstiling af superledende tråde og bånd ved hjælp af pulver-i-rør-teknologien, hvorved en sammensætning, der består af et kapperør af normalledende materiale og et deri indeholdt pulver af en superledende forbindelse eller af et forprodukt til en sådan forbindelse, forarbejdes til superiedende tråd eller bånd ved hjælp af trin med omformning og varmebehandling, kendetegnet ved, at forarbejdningen tilføres en sammensætning, der i kapperøret indeholder en pulverformet superledende MgB2-forbindelse eller et pulverformet forprodukt til en superledende MgB2-forbindelse, idet det pulverformige forprodukt er blevet anbragt i kapperøret som et mekanisk legeret pulver, der kun partielt er reageret til en MgB2-forbindelse, eller er blevet anbragt i kapperøret som en pulverblanding, der består af den ønskede MgB2-forbindelses enkeltkomponenter. 2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der anvendes en færdigreage-ret MgB2-forbindelse eller et MgB2-forprodukt, hvor der i de aktuelle krystalgitre er indbygget Al, Ag, Cu, Au, Sc, Y, Dy, Gd, Hf, Ti, Zr, Ta, V, Nb, Cr, Mo, Mn, Os, Ru, C, Si, N og/eller O. 3. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der anvendes en enkelt-komponent-pulverblanding, som består af Mg- og B-pulvere. 4. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der anvendes en enkelt-komponent-pulverblanding, som - ud over af Mg- og B-pulvere - består af et eller flere metalpulvere blandt Al, Ag, Cu, Au, Sc, Y, Dy, Gd, Hf, Ti, Zr, Ta, V, Nb, Cr, Mo, Mn, Os og Ru. 5. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der anvendes pulvere med en snæver kornstørrelsefordeling omkring en middelpartikelstørrelse d < 10 pm. 6. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der anvendes pulvere med snævre kornstørrelsefordelinger omkring to middelpartikelstørrelser, der adskiller sig med en faktor 5-10. 7. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der anvendes kapperør af Cu, Ag, Ta, Nb, Mo, W, Fe eller Mg eller af legeringer heraf. 8. Fremgangsmåde ifølge krav 1, kendetegnet ved, at et anvendt kapperør af Mg er omhyllet af yderligere et kapperør, der fortrinsvis består af Fe, Nb eller Ta. 9. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der gennemføres en eller flere varmebehandlinger ved temperaturer mellem 300 og 1100 °C i en inaktiv gas med ringe iltpartialtryk eller ringe reducerende tilsatse, som H2, til afspænding af kapperøret i relation til sammensætningens omformning og/eller dannelsen af den superledende MgB2-forbindelse af MgB2-forproduktet og/eller sintringen af den superledende MgB2-forbindelse i den komprimerede sammensætning. 10. Fremgangsmåde ifølge krav 9, kendetegnet ved, at varmebehandlingen til afspænding af kapperøret gennemføres ved temperaturer mellem 300 og 1100 °C. 11. Fremgangsmåde ifølge krav 9, kendetegnet ved, at varmebehandlingen til dannelsen af den superledende MgB2-forbindelse af et pulverformigt forprodukt, som består af et mekanisk legeret pulver, som kun partielt er reageret til en MgB2-forbindelse, gennemføres ved temperaturer mellem 300 og 700 °C. 12. Fremgangsmåde ifølge krav 9, kendetegnet ved, at varmebehandlingen til dannelsen af den superledende MgB2-forbindelse af et pulverformigt forprodukt, som består af en pulverblanding af enkeltkomponenterne i den ønskede MgB2-forbindelse, gennemføres ved temperaturer mellem 400 og 1000 °C. 13. Fremgangsmåde ifølge krav 9, kendetegnet ved, at varmebehandlingen til sintringen af den superledende MgB2-forbindelse i den komprimerede sammensætning gennemføres ved temperaturer mellem 500 og 1000 °C. 14. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der til komprimeringen af sammensætningen anvendes en HIP-proces ved temperaturer over 500 °C og tryk over 2 bar.
